Sea of Green (SOG) vs Screen of Green (ScrOG)

A great deal of confusion exists regarding the difference between Sea of Green (SOG) vs Screen of Green (ScrOG) methods of growing cannabis. Before I present what I consider to be some of the better "How to ScrOG" Guides, allow me to briefly define the difference between SOG and ScrOG.

SOG - SOG is used to create "perpetual harvests". The method involves high plant counts per cu ft and short grow cycles. Clones are introduced to 12/12 flowering with little to no veg cycle. Trellis or other screen material may be used to support heavy colas but no plant training techniques are used. Many growers cannot use SOG due to local plant count limitations.

Sea of Green (SOG), multiple plants

ScrOG - The ScrOG method involves lower plant counts, typically 1 plant per 2'x2' area. Veg periods vary, with longer veg periods resulting in canopies larger than 2'x2'. Screens are used to facilitate plant training which results in short bushy plants with virtually all target bud sites in the best lighting zone. ScrOG method is touted to produce 2 to 3 times the yield of traditional growing methods.

Screen of Green (ScrOG), single plant

There are a number of variations of the ScrOG method. We have scoured the internet and selected what we consider to be some of the better "How to Guides" below.

Argument for single plant ScrOG

The original Screen of Green (ScrOG) was invented and popularized by Wolf Segal of Portland, Oregon. Previously, underground growers (including Wolf) would use SOG (Sea of Green) to ensure perpetual harvests. SOG puts several plants under one screen. Wolf was arrested and jailed during operation "Green Merchant" in the 90s and gained the distinction of having the highest plant count in history. Wolf then came up with the concept of ScrOG to dramatically reduce plant counts and at the same time maintain high yields.

Growers who have embraced the concept of ScrOG have found far more benefits than just reducing plant counts.

Why do many growers prefer single plant ScrOGs?

Ease of providing individual plant care - When 2 or more plants are placed under a single ScrOG net, those plants are typically treated the same out of necessity. Growers have trouble getting to plants at the far reaches of the grow. All plants are treated the same despite their strain maturity level or health.
Simple to move around if necessary - If you need to pull a plant from a grow for any reason, you need to cut the net and remove it, leaving remaining plants unsupported.
Improved light distribution - Growers can rotate, custom adjust heights, plants grow at different rates and mature a different rates.
Easy to remove troubled plant from grow space, lowers risk of damage to remaining crop
Easier to water and flush
Allows gardener to harvest plants individually at precise maturity
Eliminates crawling under nets/wire mesh
Wheel chair / handicap accessibility
Irrigation equipment accessibility
A single plant can be scrogged at an optimal time in its growth cycle. Otherwise, only the most aggressive growing plants enjoy the full benefit of Screen of Green.
